Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The graph highlights major percentiles, such as 75%.

The one that struck me though was the value for age 60, because that’s clearly when the graph starts to flatten out, which means it’s when things started to really grow.

And, as one would expect, it lines up pretty perfectly with the young end of the boomer generation. That is, those born ~1960 and earlier have overseen 80-90% of all global emissions.

And if you’re an early boomer ~1945-1950, then ~80% has happened since you’ve been able to vote.

And these people also had the most exposure to airborne lead from leaded gasoline. So no wonder we have such limited intellectual capabilities.
